Introduction
There are six major kinds of variation in the structure of verb phrases. These are:

Tense:
Present (sees)
Past (see)
Aspect:
Unmarked (also called simple aspect) (sees)
Perfect (has seen)
Pregressive (is seeing)
Perfect progressive (has been seeing)
Voice
Active (sees)
Passive (is seen)
Modality
Unmarked (sees)
With modal verb (will/can/might see)
Negation
Positive (sees)
Negative (doesn´t see)
Finite clause type (also called “mood”)
Declarative (you saw)
Interrogative (did you see?)
Imperative/subjunctive (see)

Chapter six concentrates on the first four kinds of variation in the verb phrase: tense, aspect, voice and modality. These structures can be combined in numerous ways. For example, the verb phrase will be eating has a modal + progressive aspect, and have been eaten has perfect aspect + passive voice. The parts of the verb phrase follow a consistent order: | (modal) | (perfect)(form of have) | (progressive) (form of be) | (passive)(form of be) | Main verb | Example: | will | Have | been | being | eaten |

Verb phrases with all these structures are extremely rare, but are possible.
The variations in the verb phrase are related to many differences in meanings.
The complex relationship between form and meaning is easy to see by contrasting verb tense and time meaning. For example:
▪ Present (habitual) time with present tense
He goes there a lot.
▪ Past time with present tense (the historic present)
I wanted just a small box. He wasn´t satisfies with it – He goes and makes a big one as well.
In terms of time, different forms can be used to express the same meaning. For example:
▪ Future time with present tense
Future time with a present tense
Future time with a present tense
Goalkeeper Stephen Pears goes into hospital tomorrow for an operation on a cheekbone injury.

Future: modal will + infinitive verb tense
Future: modal will + infinitive verb tense
▪Future time with modal will
